You do realize you 110% contradicted yourself there, right? 800Mhz is stock on the 7950. 1100MHz is EASILY doable on the 7950, most will do 1150 completely stable. So that's 300-350 over stock.
925 is stock on a 7970. Again, most will pull off at least 1125-1150 stable at the very least. That's 200-225 over stock.

Yeah my bad, I was going from the stock figures of my card, which is 900mhz. Excuse me.

But anyway, the part of his post about every card being able to hit 1125MHZ right out of the gate on stock fan profile is a load of crap anyway.
Yeah the cards are good overclockers, but not all on stock voltage and/or stock fan profiles.

Hey guys.
Anyone else experiencing really poor performance in Diablo 3 with their 7970's?
I'm running the rig in my sig, CrossFire 7970's, both at 1000/1425.
I'd expect $1000 worth of graphics would be able to run it smoothly, but that's not the case. Every now and then it stutters and jitters, and it can be anywhere. But especially on the "Bridge of Korsikk" in Act III whenever the screen is getting overrun with creeps. Then it gets really bad, and my fps drops to about 5 fps.
My cousin running Tri-fire 5870 never ever experience any problems at all.....
I've tried 11.12, 12.4 and 12.6, but it's the same deal with all of them.
A friend of mine with a 7970 is having problems in the exact same way I am.
I hope you guys can help, because I'm sick and tired of this kind of performance in a game like this........

if you are using vsync, remove that frame rate cap when in the foreground. i think the default is 150, just remove it, or put it at 200. Background fps can be at default... i think 8. On both my 7970 and my gtx 570 i had stutters when frame cap was at 150, but after removing the cap its silky smooth! Also, do not use any fps cap in software or D3Doverrider!

I asked this before but havent gotten a reponse :
how is the performance in Max Payne 3 with only a single 7950 ?
Should I get a second card for this game to run smooth on pretty high settings ?

pretty good considering rockstar's past history with PC ports of their games. The lowest I've seen is about 117fps with peaks into the 300s and 400s but mainly stays within 150 - 250fps...and at 1920x1080.

note: i have clocked 7950 OC to 1100/1250/1237 (core/memory/VDDC (mV)) and i have 3 24" 1080p monitors connected and so if i had only 1 monitor the average fps range would be higher (the card is clocked higher since having 3 monitors reduces the fps within games and i wanted similar fps to that of a single monitor setup).

i am also using the retail version and i have not seen the patching issues when starting the game. so generally i am impressed with the performance of the game.Edited by thegh0sts - 6/6/12 at 6:35am

Disable one of your GPUs for Diablo3. The game can be maxed out on a 7750, so you won't lose anything. My single one maxes to 60 and never drops. Shoot, my temperatures don't even increase on my card/cpu in my watercooling loop with D3. Idle of 33, Load of 38C on CPU and idle of 29 on the GPU, load of 30C. lol
